Background process/multithreading in PHP??

[cricketunes@yahoo.com]

Hi Folks,
I use PHP for a user login application and it works fine. The problem
is that another process should start up as soon as the user logs in and
should keep on displaying different popup messages every 5 minutes. Is
there a way I can implement this using PHP?

Basically the idea is to get a background process running, thats it.

thanks
Cricket

Hi,

The easiest way to annoy your visitors with popups is javascript.
You don't need any background PHP process, which don't even exist AFAIK.

With JS you can easily make a timer that will popup some page every X
seconds. Beware however that many people have popupblockers, just because
unsolicited popups are an annoyance.

PHP is a serverside language. HTTP is a strict client-server stateless
protocol - a process created serverside can initiate communication with
the client via HTTP.

You could create a mini-script and prepend it to every other page
which:

1) checks when the user last accessed a page
2) if its more than 5 minutes ago insert javascript to ctreate the
popup in the current page

but beware of messing up the headers from the subsequent page.

To output so many pop ups with JavaScript would be impossible, you
should defiantly use Fortran. That's the ticket. ;)

That's why one should use in-page DHTML ads instead. They're far harder
to defeat. Got Javascript disabled? That just means you can't close the
ad window, sucker!

So you use adblock, unless you are stuck with an old browser....

you don't need a background process
well, if you want to display the popup while the user is navigating,
just use a Session variable (with the time when the next popup should
appear).
